Some time ago i made a Thread about how ZMA kept me awake. I was afraid to try it again, but recently i've been experimenting just with magnesium at night. It made it very difficult to sleep: I just stay awake for hours... I think magnesium may be too energizing (at least for me). So I decided to take it at mornings before breakfast and i have no trouble sleeping.
Now i have to decide when to take the Zinc and B6...
PS: The magnesium is chelated, from Solaray.
UPDATE: Last night i decided to try only Zinc+B6 without magnesium. Guess what? I stayed 2 hours awake in bed just trying to sleep!
Final Conclusion: I don't know why, but BOTH Zinc and Magnesium make me stay awake for 1-3 hours.
Maybe it's because they both are detrimental to Calcium absorption. Who knows, maybe after all im low in calcium...
Either way, i'll take magnesium and zinc at mornings and calcium during the day.
